Abstract
Schistura larketensis, a new species of cavernicolous loach, is described from Khung, a limestone cave in Meghalaya, India. The species differs from Schistura papulifera, its only troglomorphic congener from northeast India, in having a smooth ventral surface of the head, the presence of a small cylindrical axillary pelvic lobe, and the presence of three pores in the supratemporal canal of the cephalic lateral-line system. Apart from these differences, the species can be immediately distinguished from all other species of Schistura from the Brahmaputra River and neighboring basins by the complete absence (or only vestigial presence) of eyes.

Keywords: Pisces, cavefish, new species, Krem Khung, Krem Synrang Pamiang

FIGURE 2. Live colouration of Schistura larketensis, GUMF uncat, about 52 mm SL; India: Meghalaya: Krem Khung.

Schistura larketensis, new species

Etymology. The species name is derived from the ‘Larket’ village, the locality of Krem Khung. This name is proposed so as to encourage the village to take up biodiversity conservation as it is already in the process of constituting a Biodiversity Management Committee under the Indian Biodiversity Act.

Habitat. The new species was collected from a small stagnant pool a few square meters in area and about 1 m in depth, located in a wet passage some 500 m from the main entrance of Krem Khung. The pool bed is mostly sandy with scattered pebbles (Fig. 5). The water was clear, pH 8.6, and a very low D.O. of 1.1 ppm when analyzed in the month of April 2015. No other macrofauna were recorded inside the cave except weakly-pigmented crabs and crayfish, crickets, cockroaches and millipedes.

Distribution. ...., East Jaintia Hills District, Meghalaya, India.

[Arachnida • 2018] Annotated Checklist of Gonyleptoidea (Opiliones: Laniatores) Associated with Brazilian Caves

Giupponia chagasi Pérez & Kury, 2002

in Ázara & Ferreira, 2018.

  DOI:  10.11646/zootaxa.4439.1.1 

Abstract  

In Brazil, the order Opiliones has been well studied, making this country the leader in research with the group, but few extensive works have been made on the distribution of harvestmen associated with caves. In this context, the present paper aims to list all records of the superfamily Gonyleptoidea associated with Brazilian caves, using records from the literature and unreported data from scientific collections. The compiled checklist contains the largest number of harvestmen species recorded for caves in one country, worldwide. A total of 155 species belonging to 7 families were recorded from 952 caves throughout 152 municipalities and 17 states of Brazil. A considerable number of 46 putative (undescribed) new species were recognized, including 9 troglomorphic species. Additionally, 161 new municipal records where found for 58 known species. The most diverse family was Gonyleptidae (104 spp.), with the subfamilies Pachylinae (55 spp.), followed by Goniosomatinae (18 spp.) and Mitobatinae (16 spp.). The number of described species analysed in the present work represents about 12% of the Brazilian opiliofauna of Gonyleptoidea, with many species widely distributed, being indicative of affinity of the group with the cave environments. Thus, the compilation of distribution data of such species (mainly the troglobitic and troglomorphic) can directly contribute to a higher valuation of their habitats, leading to better preservation policies, as well as being useful for future ecological and biogeographical studies.

[Fungi • 2018] Lamprospora sylvatica (Pyronemataceae) • A New Bryophilous Ascomycete on Dicranum montanum

Lamprospora sylvatica Egertová & Eckstein

in Egertová,  Eckstein, Sochor & Vega, 2018.

DOI:  10.11646/phytotaxa.357.1.2 

Abstract

Lamprospora sylvatica is described as a new species based on finds from Ukraine, Slovakia, Germany and Norway. It is characterised by the combination of the following features: pinkish, orange to reddish-orange apothecia with a fimbriate margin, globose ascospores with more or less regular areolate ornamentation, infecting strong rhizoids of Dicranum montanum with an infectious structure consisting of a one-celled appressorium surrounded by a multi-layered cluster of thick-walled cells and haustorium within the rhizoids. The apothecia were always found on rotten wood, which is an unusual habitat for hosts of bryophilous Pezizales. The new species is compared to similar taxa morphologically and by means of DNA sequencing. In the phylogenetic analysis based on LSU and ITS regions, L. sylvatica forms a well-supported clade close to L. feurichiana (on Ceratodon purpureus), L. kristiansenii (also on C. purpureus) and L. campylopodis (on Campylopus spp.).

Abstract

A reassessment of the taxonomy of Lygosoma bampfyldei based on morphology and color pattern indicates that it is a species complex containing L. bampfyldei Bartlett, 1895 from the Rajang River, Sarawak and Croker Range, Sabah in East Malaysia; Lygosoma peninsulare sp. nov. from Bukit Larut, Perak and 13.5 km east of Jeli, Kelantan, Peninsular Malaysia; Lygosoma kinabatanganensis sp. nov. from the Kinabatangan District, Deramakot camp (=Deramakot Sabah Forestry Department), Sabah, East Malaysia; and L. schneideri Werner, 1900 from Djapura, Indragiri, Sumatra, Indonesia—resurrected herein from the synonymy of L. bampfyldei. The new taxonomy aligns itself well with a growing body of literature demonstrating that semi-fossorial and fossorial Sundaic skinks are more diverse than previously considered.

Abstract

Sindora stipitata, a new species in the subfamily Detarioideae (Leguminosae), collected from Nakhon Phanom Province, Thailand, is described and illustrated. The new species is morphologically similar to S. leiocarpa but differs in its smaller stature (3–5 m high), 6-foliolate paripinnate leaves, falcate persistent stipules, presence of a petal auricle, absence of a petal claw, stipitate ovary and capitate stigma. A key to the Thailand and Malesia species of Sindora is provided.

Taxonomy

Sindora stipitata Chatan & Promprom, sp. nov.

Diagnosis: Sindora stipitata is very similar to S. leiocarpa from Malesia, but it is easily distinguished by the following characters: a smaller stature (3-5 m high), 6-foliolate paripinnate leaves, falcate persistent stipules, presence of a petal auricle, absence of a petal claw, stipitate ovary and capitate stigma.

Distribution: The new species is a Thai endemic and is known from only the type locality in the Phulangka National Park, Ban Pheang District, Nakhon Phanom Province, North-eastern Thailand.

Ecology: This new species grows in open areas of dry deciduous forest at an elevation of 250–350 m.

Etymology: The specific epithet refers to its distinctly long ovary stipe. This character is one of many morphological characters that distinguishes the new species from its closely related species.

Vernacular name: Ma Kha Tae Nakhon Phanom - มะค่าแต้นครพนม, Mak Tae.

Preliminary conservation status: Sindora stipitata is known only from the type locality and its estimated extent of occurrence is less than 100 km2. The number of mature individuals was less than 1,000 and the occupied area is continuing to decline slightly. Therefore, it should be considered as “Critically Endangered” according to the IUCN criteria B1 (IUCN 2017).

[Botany • 2018] Taxonomic Revision of the Genus Calendula (Asteraceae) in the Iberian Peninsula and the Balearic Islands

Calendula suffruticosa Vahl (1791)

in Gonçalves, Castro, Paiva, et al., 2018.

DOI:  10.11646/phytotaxa.352.1.1 

Abstract

A taxonomic revision of the genus Calendula is presented, based on an extensive analysis of its morphological variation, which allowed a re-evaluation of the species delimitations in the Iberian Peninsula and the Balearic Islands. Morphometric data based on field and herbarium material were gathered and analysed. Characters traditionally used to delimit taxa in the genus were re-evaluated, and the taxonomic value of new characters was explored. The variation between and within taxa was explored statistically. Morphological patterns were compared with chromosome numbers and genome size estimates. The results revealed that the achenes are particularly important to distinguish taxa, although, due to their variability, they should be used carefully. Four species are recognised in the area (C. arvensis, C. officinalis, C. tripterocarpa and C. suffruticosa), including nine subspecies of C. suffruticosa. Among these, two new subspecies (C. suffruticosa subsp. trialata and C. suffruticosa subsp. vejerensis) are described. Identification keys, descriptions, geographical distributions and conservation assessments are also provided for each taxon.

[Herpetology • 2018] Molecular Phylogeny and Diversification of Malagasy Bright-eyed Tree Frogs (Mantellidae: Boophis)

in Hutter, Lambert, Andriampenomanana, et al., 2018

  DOI: 10.1016/j.ympev.2018.05.027 

Highlights

• We estimated the first multi-locus phylogeny of Boophis frogs.

• Found that the B. ulftunni group was nested within the B. majori group.

• We erect the new B. blommersae group, composed of small, brown stream breeding frogs.

• We illustrate examples of correlated and repeated evolution in coloration and ventral transparency.

• Boophis diversified within the Eastern highland forests of Madagascar.

• Adaptation to these highland areas was important in their diversification.

Abstract

We investigate the molecular phylogeny of Boophis, a group of arboreal frogs from the Malagasy-Comoroan family Mantellidae. Based on newly acquired DNA sequences of five mitochondrial and five nuclear markers (7444 base pairs), we infer a phylogeny of Boophis with complete species-level taxon sampling. We reconstruct the phylogeny using Bayesian inference and maximum likelihood and estimate divergence dates for the major clades of the genus. The phylogenetic analyses together support the monophyly of the two subgenera (Sahona and Boophis), and provide strong support for most previously identified species groups, except that the B. ulftunni group is nested within the B. majori group. We also erect a new species group related to the B. mandraka group, the B. blommersae group, composed of small-sized, brown stream-breeding frogs previously included within the B. majori group. Finally, we use the resulting phylogeny to illustrate striking examples of repeated evolution of coloration and ventral transparency and address the biogeographic history and broad pattern of species diversification in the genus. Ancestral area reconstructions provide evidence that Boophis diversified within the Eastern highland forests of Madagascar, and we suggest that adaptation to these highland areas was important in their diversification.

  Summary

Ceylon Junglefowl was described in 1807 by the Dutch ornithologist Coenraad Jacob Temminck. The specimens he examined were tailless (‘rumpless’) and therefore he named them Gallus ecaudatus. In 1831 the French naturalist René Primevère Lesson described a Ceylon Junglefowl with a tail as Gallus lafayetii (= lafayetii), apparently unaware of Temminck’s ecaudatus. Subsequently, ecaudatus and lafayetii were realised to be the same species, of which G. stanleyi and G. lineatus are junior synonyms. However, Charles Darwin tried to disprove the existence of wild tailless junglefowl on Ceylon in favour of his theory on the origin of the domestic chicken. 

‘The tailless cock inhabits the immense forests of the island of Ceylon’ (Temminck 1813: 268). 

 ‘… but this statement [tailless fowls are wild in Ceylon] … is uterly false’ (Darwin 1868: 259).

Figure 2. Lithograph of Gallus ecaudatus, based on specimen RMNH. AVES.224888, by Jean-Gabriel Prêtre prepared c.1806 for an illustrated work in three volumes that Temminck intended to publish on pigeons and Galliformes. Only the volume on pigeons was published, in 1808, and the two volumes on Galliformes never appeared due to a confict between Temminck and the French illustrator of the frst volume, Pauline Knip (Dickinson et al. 2010). Instead, Temminck later published Histoire naturelle générale des pigeons et des gallinacés in three volumes (1813–15) without any colour illustrations. The reference ‘Gall. v. 1. pl. Enl.’ in Temminck’s published catalogue (1807) refers to the frst of the two unpublished volumes on Galliformes, which would have been vol. 2 of the complete work (Naturalis Biodiversity Center, Leiden)

[Mollusca • 2017] Erhaia wangchuki • Erhaia Davis & Kuo (Gastropoda, Rissooidea, Amnicolidae) also in Bhutan

Erhaia wangchuki

Gittenberger, Sherub & Stelbrink, 2017

 DOI:  10.3897/zookeys.679.13326 

Abstract

The occurrence of at least one species of Erhaia in Bhutan, viz. Erhaia wangchuki sp. n., is confirmed by DNA sequencing. A second unnamed species from Bhutan, that might be congeneric, is known from only a single shell. According to the molecular analysis, E. wangchuki is most closely related to a still undescribed Erhaia species from China. These two species together with E. jianouensis and Akiyoshia kobayashii, both also from China, form a well supported clade. Awaiting additional molecular data, the apparent inconsistency regarding Erhaia versus Akiyoshia is not dealt with here. The extant true sister species of E. wangchuki could be among the four SE Himalayan species from Bhutan and Nepal that are classified with Erhaia on the basis of conchological data only.

Abstract

Chamaelirium viridiflorum (Melanthiaceae), a new species from southern Jiangxi, China, is described and illustrated. It is similar to C. koidzumiana in their ellipitic or ovate leaf blade and slender petiole, but differs by its zygomorphic flowers and unequal tepals. Besides Chamaelirium viridiflorum is also similar to C. shiwandashanensis in their actinomorphic flowers, but distinguished by its spatulate to obovate leaf blade, distinct petiole and 0.8–1.1 cm long tepals. This new species has an obvious feature that the color of tepals is still greenish at the end of the flowering period.
